Safety Precautions

All external equipment which is connected to the machine must be CE/EMC-approved

and connected using an approved shielded cable.

Safety Precautions

The machine is only intended for water-wash use.

Do not allow minors to use the machine.

Do not hose down the machine with water.

The machine's door lock must under no circumstances be bypassed.

If the machine develops a fault, this must be reported to the person in charge as soon

as possible. This is important both for your safety and that of others.

The machine is not intended to be used by people (including minors) with reduced

physical or mental capacity or lack of experience and knowledge. Such people must

be instructed in the use of the machine by a person who has responsibility for their

safety. Minors must be supervised to ensure that they do not play with the machine.

Warnings

The service manual contains the following warnings concerning serious personal injury.

Next to each warning is a reference to the page and section where the warning text is located

in the manual.

DANGER

Take care when measuring the motor control system since all components have a

potential difference of approximately 300V in relation to protective earth and neutral.

The components will contain dangerous voltages when the green LED on the motor

control board is on.

The motor control system will remain live for 10-30 seconds after cutting the power to

the machine and the motor has stopped running.

Description

General

The machines covered in this service manual

include the following models:

85 W485M/N

The machines feature an electronic programme

unit with ﬁxed washing programmes that may be

changed using optional accessories. The pro-

gramme unit also has an in-built self-diagnosis

programme, which increases the possibilities for

quick troubleshooting.

The motor is frequency-controlled and is control-

led by an advanced motor control. This allows

precise and ﬂexible control of the motor rpm for

any application.

The machines are supplied to customer speciﬁ-

cations with e.g. electric or steam heating or no

heating, and may be connected to various com-

binations of cold, warm and hard water.

Function

General

This section presents a general overview of the functions of the machine.

Most functions are then presented in detailed in separate chapters later on

in this service manual.

The machine is freely suspended, which means the outer drum and motor

are mounted on a supporting ”cradle” that rests on four shock absorbers

for dampening the imbalance in the machine.

The washer drum (inner drum) is belt driven by a motor. This motor is loca-

ted at the bottom of the machine and is mounted on the cradle with a belt

tensioner. The inner drum is mounted to the outer drum at the rear plate

with two bearings sealed against leakage with sealing rings.

The drain valve is a water-controlled diaphragm valve alternatively, an

electrical drain valve or drain pump.

The door is of sturdy type that is interlocked with a lock module when in

operation.

The control panel contains a program knob for selecting the ﬁxed wash

programs and a display.

The program unit is mounted inside the control panel. Contactor, water

valves, etc., are located at the back of the machine.

Program unit

The control panel contains a program knob and

a display. The panel can also be equipped with

two preset buttons.

The control panel and display are used by:

• theusertoselectthemachine’sxedwash

programs, to select up to two options for

each wash program and for information on

the wash process and any fault indicators.

• servicepersonnelfornavigationandcontrol

oftheprogramunit’sserviceprogram.

• programmingpersonnelforsettingandpro-

gramadjustmentintheprogramunit’ssoft-

ware.

If present, the preset buttons are used for direct

start of two preset wash programs.

Using information on torque values from the

motor, the weight of each wash is measured

before each wash program in order to adapt the

amount of water used for washing.

The program unit controls the water valves, drain

valve and heating via an I/O board in the rear

electrical module. Control signals to external

units, such as detergent pumps or external water

valves can also be engaged here.

Motor and motor control

The washer drum (inner drum) is belt driven by a

frequency controlled motor. The motor is located

on a motor shelf under the outer drum and has

been arranged with a belt tensioner.

Motor control is microprocessor controlled and

can control the acceleration of the drum, its rpm

and its retardation very precisely.

Motor control communicates with the program

unit through a serial interface.

Themachine’smotorandmotorcontrolarede-

scribed in more detail in the section Motor.

Door lock

The door lock is electromechanical with twin sa-

fety breakers. The lock is bi-stable, i.e. the lock

must be given an active signal from the program

unit to lock as well as unlock the door.

A separate circuit integrated in the program unit

checks and controls the locking and unlocking

of the door through a lock module. The circuit

has separate controls that the drum is empty

and that it is stationary. Through sensors in the

lockmodule,thecircuitchecksthedoor’sclo-

sed and locked position. Together with other

controls the program unit conducts, this will

guarantee the door cannot be opened by mis-

take.

Heating

Electric heating heats the washing water with

three elements accessible from the front of the

machine.

Themachine’sheatingsystemisdescribedmore

thoroughly in the section Heating.

Water connections

The machine can have one, two, three or four wa-

ter inlet valves depending on the machine size and

customer requirements.

In this unit there are also eight connections for an

external detergent feeder.

Rear electric module

Contains the main switch or terminal block for

incoming power, heating contactor, I/O board with

drain valves and heating. Some machines have an

additional I/O board with terminal blocks for con-

necting e.g. external detergent feeder.

Detergent compartment

The detergent compartment has four compart-

ments for prewash, main wash, rinse and

bleaching agent/liquid detergent.

Themachine’sdetergentcompartmentisdescri-

bed more thoroughly in the section Detergent

compartment.

Drain valve

The valve is a diaphragm valve that is opened

and closed through water pressure. The control

valve is mounted by the water valves.

Themachine’sdrainvalveisdescribedmore

thoroughly in the section Drain valve.

Frame and suspension

The machines are freely suspended, i.e. the

drum package can move and is suspended in

relation to the frame. In this way, a minimum of

vibration passes to the bottom plate, which in

turn simpliﬁes installation as a concrete founda-

tion is not required.

The machine has four shock absorbers between

the bottom plate and the drum package.
